Chapter-4 Maps

Explanation:

 Maps are pictures. They shrink the entire universe or a portion of it so that it will fit on a piece of paper. To put it another way, maps are created at smaller scales. But in order to maintain the distance between the real sites, it must take great care when performing this reduction task. Only when a tiny distance on paper corresponds to a great distance on the ground is it possible. A scale is employed for this reason.

The scale is the ratio of the distance between the actual location and the location depicted on the map. An illustration will help us comprehend this. Let's say there are 8 kilometres between your coaching centre and school. If you distort the 8 km distance on a map by 2 cm. This implies that 1 cm on the map corresponds to 4 km on the ground. As a result, your drawing will be scaled at 1 centimetre = 4 km. With any map, scale is crucial.

Calculating the distance between any two points on a map will be simple if scale is known. On a piece of paper, a small scale is used to represent enormous areas like continents or nations. 10 centimetre of the map, for instance, represents 1000 km of the terrain. On paper, a tiny place like a town or village is depicted at a large scale. As an illustration, 10 centimetre on the map only depicts 1000 metres above the ground.

Explanation:

An essential part of a map is the direction. The upper right corner of most maps has an arrow with the letter "N" on it. This arrow points in the direction of north. The north line is the name of it. After determining the north direction, it is simple to determine the east, west, and south directions.

Four main directions exist: North, South, East, and West. They're referred to as cardinal points. There are four further intermediate directions in addition to these. These directions are north-east (NE), south-east (SE), south-west (SW), and west (NW) (NW). With the use of these intermediate directions, it is possible to locate any location more precisely.

Explanation:

It may not be possible to depict many features on a map in their exact size and shape, such as buildings, roads, etc. As a result, they are depicted utilising particular letters, hues, colours, images, and lines. These are symbols that pack a lot of meaning into a small package.

Maps may be simply produced and read with the help of these symbols. When we are unable to ask for directions because we do not speak the local language, these symbols are of tremendous assistance. With the use of these symbols, we may get data from maps.

All people can understand and speak the language of maps. Regarding the use of these symbols, there is an international agreement

Explanation:

a. A collection of maps called an atlas.

b. The natural characteristics of the globe, such as mountains, plateaus, plains, rivers, and oceans, are depicted on political maps.

c. Political maps display cities, towns, and villages as well as the borders of many nations and world regions.

Explanation:

a. The term "thematic map" refers to a map that focuses on a particular piece of information. Road maps, industry distribution maps, etc. are a few examples.

b. A big scale map is used to depict a small area, such as a hamlet or town, whereas a small size map is used to depict enormous areas, such as continents or countries.

c. A map at a big scale provides more information than one at a small scale.

d. On most maps, the upper right corner has an arrow with the letter "N" on it. The north line is the arrow that points in the direction of the north.

Explanation:

1. A compass is a tool used to determine general directions.

2. Certain symbols have a predetermined meaning and are universally recognised. They are referred to as conventional symbols.

3. A sketchy drawing of a location is a sketch map. It is not scaled in the drawing.

4. A plan is a large-scale sketch of a small region.

Explanation:

(i) A big scale map is used to depict a small area, such as a hamlet or town, whereas a small size map is used to depict enormous areas, such as continents or countries.

(ii) A map at a big scale provides more information than one at a small scale.

Explanation:

The cardinal points are the four principal directions of North, South, East, and West. There are four intermediate directions in addition to these primary ones: north-east (NE), south-east (SE), south-west (SW), and north-west (NW). The intermediate directions are highly useful for more precise location.

Explanation:

 (a) A map is made up of three elements: distance, direction, and symbol.

(b) North, South, East, and West are the four cardinal directions.

(c) The ratio between the actual distance on the ground and the distance depicted on the map is the scale of the map. According to scale, maps can be divided into two categories: large scale maps and small scale maps.

(d) A map is a depiction of the earth's surface or a portion of it rendered on a flat surface in accordance with a scale. A spherical shape cannot be scaled and flattened. Maps are therefore more useful than a globe.

(e) The following list explains how a plan differs from a map.

(f) Detailed information is provided by large-scale maps.

(g) Symbols use specific characters, shades of grey, colours, images, and lines to depict things like highways, bridges, trees, railway lines, etc. In this way, symbols make it simple to understand a map.

Explanation:

Maps are more practical than globes, because A map is more practical than a globe since it makes it simpler to find a specific spot. Flat maps are simpler to carry. They are also more practical for determining distances. You may view the entire world at once on a flat global map. That makes it easier to comprehend how each nation compares to the others.

Explanation:

a. A scaled representation of the earth's surface, or a section of it, rendered on a flat surface, is referred to as a map.A plan is a small area represented at a large size. A big map has a lot of information on it.

b. A symbol is helpful while reading a map. They pack a lot of details into a tiny area. Symbols are helpful when trying to communicate in a language you don't understand. Despite this, finding a particular site is still simple thanks to the use of symbols.
